It was used in Germany after on March 22, 1935, using telecine transmission of film, intermediate film system, or cameras using the Nipkow disk. Transmissions using cameras based on the iconoscope began on January 15, 1936.
The Berlin Summer Olympic Games were televised, using both fully electronic iconoscope-based cameras and intermediate film cameras, to Berlin and Hamburg in August 1936. Twenty-eight public television rooms were opened for anybody who did not own a television set. After February 1937 this system was replaced by a superior 441-line system.
